Knowing that he
is talking to Arjuna he says in this shloka that there is another method of learning.
Learning by parampara. What is the meaning of parampara. In fact
there is no word in English that can explain what is the meaning of parampara.
Parampara is more like a continum or a flow as described
above. It is not the same a tradition.
It is not learning by reading the shastras, it is not part
of learning as you grow; it is a flowing. This knowing by parampara is a flow.
The knowledge Krishna is talking about in Gita is of a
different nature, a higher nature.
There are other knowings by parampara. Purohits in our
villages mostly learned by parampara.
There was no school of purohits then. It just flowed
through a system.
For thousands of years people in India have poured their
entire energy for the search of truth. You can visibly see the flow of Ganga.
